Gallia did not steal anything. They developped their own lane/gate line from the very beginning. It was just not possible to complete and implement them upon arrival of 4.85, I suppose.
Better think up how Ageira managed to keep Trade Lane/ Jumpgate secret for centuries.
HOW??!!!! What, in those centuries noone was able to develop/reverse engineer alternative? even with worse stats.
Noone was able to bribe, capture and interrogate, steal, /put your choice here/ their personnel/scientists, put a spy into production facilities FOR CENTURIES?
Are you kidding?
(well, thats more like question not to Disco, but to those who wrote freelancer lore and to quality of that lore...)
